I pushed a new build that fixes it (0.74-0maemo4) -- without workaround. This should also slightly increase the fullscreen speed on the N900.

This build also has the work I did long ago on calibration-less Win 3.11 mouse -- I extended the emulated PS2 mouse protocol so that it has a new "tablet" mode. Hopefully no games shall break, as the new protocol defaults to off.

In order to use it on Win3.x however you need a specific mouse driver that I hope to publish soon.
